Answer : The number of grams of gold Bob take from the aliens will be 0.5.
Explanation :
As we are given that:
1 zygot = 3 trigots
3 trigots = 2 bigots
4 bigots = 1 gram gold
Now we have to determine the number of grams of gold Bob take from the aliens.
The number of grams of gold Bob take from the aliens will be equal to:
[tex]\frac{1\text{ zygot}}{1}\times \frac{3\text{ trigots }}{1\text{ zygot}}\times \frac{2\text{ bigots }}{3\text{ trigots }}\times \frac{2\text{ gram gold}}{4\text{ bigots }}[/tex]
= [tex]\frac{6}{12}[/tex] gram gold
= [tex]\frac{1}{2}[/tex] gram gold
= 0.5 gram gold
Hence, the number of grams of gold Bob take from the aliens will be 0.5.

Air masses that form over large bodies of water are moist. What process determines the amount of moisture in an air mass?
Answer:
I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

Write a balanced equation for each of the acid-base reaction given below.a. Aqueous sulfuric acid with aqueous potassium hydroxide.
Answer:
H2SO4 + 2KOH => K2SO4 + 2H2O
Explanation:
The acid-base reaction is a type of chemical reaction that involves the exchange of hydrogen ions.
The acid-base reaction between aqueous sulfuric acid ( H2SO4 ) and aqueous potassium hydroxide (KOH) is a neutralization reaction that results in potassium sulfate and water.
sulfuric acid + potassium hydroxide => potassium sulfate + water
So, the balanced equation for this reaction is as follows:
H2SO4 + 2KOH => K2SO4 + 2H2O
Hence, the correct answer is "H2SO4 + 2KOH => K2SO4 + 2H2O".

What molar concentration of hydrochloric acid (HCl) is needed to prepare a disinfectant solution with a pH
Answer:
The correct approach is "3.1×10⁻³ M".
Explanation:
As we know,
[tex]pH=-log[H_{3}O^+][/tex]
[tex]pH=2.5[/tex]
[tex][H_{3}O]^+= \ ?[/tex]
Now,
⇒ [tex]-log[H_{3}O]^+=2.5[/tex]
⇒ [tex][H_{3}O]^+=10^{-2.5}[/tex]
⇒ [tex]=3.1\times 10^{-3} \ M[/tex]
So that the needed molar concentration of HCL will be:
= [tex]3.1\times 10^{-3} \ M[/tex]

In a certain chemical reaction, the bond energy of the products is 67 kJ and
that of the reactants is 52 kJ. Because energy is conserved, how much
potential energy does the system release or absorb?
O A. The reaction uses up 15 kJ of energy from the reaction system.
B. The reaction creates 15 kJ of energy when bonds form.
C. The reaction system absorbs 15 kJ of energy from the
surroundings.
O D. The surroundings absorb 15 kJ of potential energy.
D. The surroundings absorb 15 kJ of potential energy.
Further explanationChemical bonds = potential energy
ΔH reaction from bond energy is a breaking and forming reaction of the 2 reacting molecules
Can be formulated:
ΔH rxn = ∑ the energy of the reagent bonds broken - ∑ the energy of the bonds formed by the product
The bond energy of the products is 67 kJ and reactants 52 kJ
[tex]\tt \Delta H_{rxn}=52-67=-15~kJ[/tex]
ΔH = negative ⇒The reaction is exothermic(releases heat to surrounding)

How many grams of glycine amide should be added to 1.00 g of glycine amide hydrochloride to give 100 mL of solution with pH 8.00
Answer:
0.4235 g of glycine amide should be added
Explanation:
From the given information:
The equation of the reaction can be illustrated as:
[tex]BH^+ \to B^+ + H ^-[/tex]
where:
mass of glycine amide hydrochloride = 1.00 g
Suppose x be the amount of (in grams) of glycine amide that is required to be added; Then:
[tex][BH^+] = \dfrac{1.00 \ g}{110.54 \ gmol \times 0.100 L}[/tex]
[tex][BH^+]=[/tex] 0.0905 M
So, For [B} i.e, for glycine amide
[tex][B] = \dfrac{x \ g}{74.083 \ gmol \times 0.100 L}[/tex]
[B] = 0.135x M
∴
[tex]\dfrac{[B]}{[BH^+]}=\dfrac{0.135x \ M}{0.0905 \ M }}[/tex]
[tex]\dfrac{[B]}{[BH^+]}=1.49x[/tex]
The log of the above question can be computed as:
[tex]log _{10}\dfrac{[B]}{[BH^+]}=log _{10}1.49x[/tex]
[tex]pH = pK_a + log _{10} \dfrac{[B]}{[BH^+]}[/tex]
8.00 = 8.20 + [tex]log _{10}(1.49x)[/tex]
8.00 - 8.20 = [tex]log _{10}(1.49x)[/tex]
-0.20 = [tex]log _{10}(1.49x)[/tex]
1.49 x = [tex]10^{-0.20}[/tex]
1.49 x = 0.631
x = 0.631/1.49
x = 0.4235 g

How many atoms of N (nitrogen) are there in 1 mole of NH4Cl?
Answer:
In one mole of NH₄Cl 6.022 × 10²³ atoms of N are present.
Explanation:
Given data:
Number of atoms of N = ?
Number of moles of NH₄Cl = 1 mol
Solution:
First we have to calculate the number of atoms in NH₄Cl .
There is only 1 mole of N in 1 mole of NH₄Cl .
Now we will calculate the number of atoms of nitrogen in one mole of N by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole of N = 6.022 × 10²³ atoms of N
Thus in one mole of NH₄Cl 6.022 × 10²³ atoms of N are present.
